LONDON: The UK Parliament is expected to be briefed by the defence minister later on Tuesday after reports of a massive data breach involving the Ministry of Defence (MoD) targeting service personnel from the Royal Navy, Army and Royal Air Force. "The UK will not tolerate malicious cyber activity targeting our democratic institutions. It is an absolute priority for the UK government to protect our democratic system and values," UK Deputy Prime Minister Oliver Dowden told Parliament at the time. "I hope this statement helps to build wider awareness of how politicians and those involved in our democratic processes around the world are being targeted by state-sponsored cyber operations. We will continue to call out this activity, holding the Chinese government accountable for its actions," he said.
